18mm OSB 3 Tongue & Groove Flooring Board 2400mm x 590mm (8' x 2')

18mm OSB3 tongue-and-groove flooring board, measuring 2400mm x 590mm (8' x 2'). Each board is manufactured from strands of softwood arranged in cross-oriented layers, bonded with moisture-resistant resin, and hot-pressed to form a dense, structural panel with excellent strength and stability. The tongue-and-groove edges are precision-machined to ensure a tight interlock between boards, helping to minimise deflection, reduce squeaks, and produce a flush, even surface ready for direct coverings. With its OSB3 classification, the panel is designed for load-bearing use in both dry (Service Class 1) and humid (Service Class 2) conditions, making it a dependable choice for flooring, flat or pitched roofing, and wall sheathing where durability and moisture resistance are critical.
